Estriol cream for vulva - what counts as 'working' for you?

I keep seeing posts where people say ‘it works’ but everyone’s measuring something different. Some are tracking symptom-free days, some talk about the tissue itself actually improving (dryness, elasticity, turgor), some just mean subjective comfort during specific activities. idk, I’m wondering what your actual metric is. Because ‘works’ is a pretty broad signal. Also - has anyone noticed whether this shifts across your cycle? Might be nothing. But I’ve been tracking hormonal timing closely and I’m wondering if topical estriol response changes between follicular and luteal phases. Like, does a week of consistent use feel more effective in one phase than another? Not asking to poke holes. Genuinely curious because the specificity usually tells you something useful. anyway.
